Flashes of what may become a transformative new technology are coursing through a network of optic fibers under Chicago.

Researchers have created one of the world’s largest networks for sharing quantum information —a field of science that depends on paradoxes so strange that Albert Einstein didn’t believe them.

The network, which connects the University of Chicago with Argonne National Laboratory in Lemont, is a rudimentary version of what scientists hope someday to become the internet of the future. For now, it’s opened up to businesses and researchers to test fundamentals of quantum information sharing.

As our tech needs grow and the Internet of Things increasingly connects our devices and sensors together, figuring out how to provide power in remote locations has become an expanding field of research.

Professor Seokheun “Sean” Choi—a faculty member in the Department of Electrical and Computer Engineering at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science—has been working for years on biobatteries, which generate electricity through bacterial interaction.

One problem he encountered: The batteries had a lifespan limited to a few hours. That could be useful in some scenarios but not for any kind of long-term monitoring in remote locations.

The US Transportation Command, or USTRANSCOM, are a Pentagon office tasked with transporting cargo to American global military assets, announced that it was partnering with SpaceX to examine the feasibility of quickly blasting supplies into space and back to Earth rather than flying them through the air.

SpaceX is already functionally a defense contractor and has launched American military satellites and recently bolstered Ukrainian communication links with Starlink.

SpaceX’s Starlink satellite internet service has let the company capture high definition video of its rocket landing on a ship.

Developed in collaboration with colleagues from China, Germany and Singapore, the new technology uses nanoparticles, so small that about 12,000 of them can fit within a cross-section of a human hair. These tiny particles are arranged into unique patterns on the slides.

Physicists at The Australian National University (ANU) have developed tiny translucent slides capable of producing two very different images by manipulating the direction in which light travels through them.

As light passes through the slide, an image of Australia can be seen, but when you flip the slide and look again, an image of the Sydney Opera House is visible. The pair of images created is just one example of an untapped number of possibilities.

In forthcoming years, everyone will get to observe how beautifully Metaverse will evolve towards immersive experiences in hyperreal virtual environments filled with avatars that look and sound exactly like us. Neil Stephenson’s Snow Crash describes a vast world full of amusement parks, houses, entertainment complexes, and worlds within themselves all connected by a virtual street tens of thousands of miles long. For those who are still not familiar with the metaverse, it is a virtual world in which users can put on virtual reality goggles and navigate a stylized version of themselves, known as an avatar, via virtual workplaces, and entertainment venues, and other activities. The metaverse will be an immersive version of the internet with interactive features using different technologies such as virtual reality (VR), augmented reality (AR), 3D graphics, 5G, hologram, NFT, blockchain, haptic sensors, and artificial intelligence (AI). To scale personalized content experiences to billions of people, one potential answer is generative AI, the process of using AI algorithms on existing data to create new content.

In computing, procedural generation is a method of creating data algorithmically as opposed to manually, typically through a combination of human-generated assets and algorithms coupled with computer-generated randomness and processing power. In computer graphics, it is commonly used to create textures and 3D models.

The algorithmic difficulty is typically seen in Diablo-style RPGs and some roguelikes which use instancing of in-game entities to create randomized items. Less frequently it can be used to determine the relative difficulty of hand-designed content to be subsequently placed procedurally, as can be seen with the monster design in Unangband. For example, the designer can rapidly create content, but leaves it up to the game to determine how challenging that content is to overcome, and consequently where in the procedurally generated environment this content will appear. Notably, the Touhou series of bullet hell shooters use algorithmic difficulty. Though the users are only allowed to choose certain difficulty values, several community mods enable ramping the difficulty beyond the offered values.

Actually transporting quantum states over significant distances is tricky, though. Researchers have had some success transmitting messages tied up in the quantum states of photons over several hundred miles of optical cables, and also using satellite quantum communication to establish links over even greater distances. But the inevitable signal losses over either mode of communication mean that scaling up to the distances required for a true internet will be tricky.

One workaround is to exploit another quantum phenomenon called teleportation. This works much like the sci-fi concept used in shows like Star Trek, allowing information to be instantaneously transmitted from one place to another, theoretically over unlimited distances. And now, researchers from the Netherlands have provided the first practical demonstration of how this could work.

The team set up three quantum “nodes” called Alice, Bob, and Charlie, which are able to store quantum information in qubits—the quantum equivalent of bits in a computer made from nitrogen vacancy centers. These are tiny defects in diamonds that can be used to trap electrons and alter their quantum state. They then connected Alice to Bob and Bob to Charlie using optical fibers.

SpaceX successfully launched satellites into orbit Friday afternoon from the Kennedy Space Center.

The Falcon 9 rocket carried 53 Starlink satellites into low orbit.

GPT-3 is a neural network machine learning model trained using internet data to generate any type of text. Developed by OpenAI, it applies machine learning to generate various types of content, including stories, code, legal documents, and even translations based on just a few input words. GPT-3 has been getting a lot of attention for the seemingly unlimited range of possibilities it offers. GPT-3 is also being used for automated conversational tasks, responding to any text. So here mentioned the 10 experiments with GPT-3.

Interviewing AI: Using the Chat preset within GPT-3 Playground you can ask the current entity about its personality. And while of your dialog, the GPT-3’s personality emerges. Note that after 2048 tokens there’s a hard cut, and you never will encounter the same personality setting again. It imitates a human person worrying about data privacy.

Doctor’s Assistant: The AI has been fed with patient files, describing their profile and symptoms in a few lines. The AI spontaneously makes suggestions of what the disease could be. GPT-3 got away with an impressive 8 out of 10 correct guesses. This could become amazing support to doctors, and a great tool to investigate.
